DRAFT

Always wear an approved anti–static wrist strap while

handling any circuit card/module to prevent damage by

ESD.

n Step Action

1 If it has not already been done, connect the LMF to the BTS (see Table 3-5 on page

3-15).

2 From the Windows desktop, click the Start button and select Run.

3 In the Open box, type ping and the <MGLI IP address> (for example, ping

128.0.0.2).

NOTE

128.0.0.2 is the default IP address for MGLI–1 in field BTS units. 128.0.0.1 is the

default IP address for MGLI–2.

4 Click on the OK button.

5 If the connection is successful, text similar to the following is displayed:

Reply from 128 128.0.0.2: bytes=32 time=3ms TTL=255

If there is no response the following is displayed:

Request timed out

If the MGLI fails to respond, reset and perform the ping process again. If the MGLI

still fails to respond, typical problems are shorted BNC–to–inter-frame cabling, open

cables, crossed A and B link cables, missing 50–Ohm terminators, or the MGLI itself.
